用Ａｒ＋激光器作光源，光导热塑料作记录介质，ＣＣＤ—微机系统作探测器，从理论和实验上研究了三个干涉图法的实时全息图的自动计算。该工作不但可以再现被测物体变形的二维等高线，也可以再现其三维变形表面，从而实现变形物体的三维测量。作为实例，测量了压力鼓的变形。 Using Ar + laser as light source, photoconductive thermoplastics as recording medium and CCD-PC as detector, the automatic calculation of real-time holograms of three interferograms is studied theoretically and experimentally. This work can not only reproduce the deformation of the measured object two-dimensional contours, but also can reproduce the three-dimensional deformation of the surface, in order to achieve three-dimensional deformation of objects measured. As an example, the deformation of the pressure drum was measured.
